That, however, is only a part of the story.
We are what we eat, and what we eat eats. That includes all the stuff consumed by the plants and the animals (unless you're vegetarian) we include in our diets.
Would we rather eat chickens raised like this...
Would we rather eat plant-based food that is raised like this...
The nutritional value of all our food is directly proportional to the quality of the environment in which it is/was raised.
We get to decide,
with each purchase,
with each mouthful.
